He also assumes that the environment in which we all live could
sustain
such levels. I don't think there is any precedent for that
assumption.

I don't think plants will complain.

How do you know? The planet has never sustained those levels.

800 ppm?

800 ppm will easily desertify the planet and melt all the ice.

increased temperature accelerates the evaporation precipitation
cycle, really, you are looking at more tropical type climates and less
desert.

Not to mention the fact that it would probably accelerate plant growth
rates (and in fact such acceleration would prevent the levels from
ever getting that high).

But don't confuse Elifritz with reality.

Then why hasn't the current level caused accelerated plant growth and kept
the
level from growing?

That wasn't what I asked. If plants growing will absorb all the CO2, why
haven't they done so already? Why is CO2 still increasing?
